This folder contains data for incremental compilation. The compiled_partitions sub-folder contains previous compilation results for each partition. As long as this folder is preserved, incremental compilation results from earlier compiles can be re-used. To perform a clean compilation from source files for all partitions, both the db and incremental_db folder should be removed. The imported_partitions sub-folder contains the last imported QXP for each imported partition. As long as this folder is preserved, imported partitions will be automatically re-imported when the db or incremental_db/compiled_partitions folders are removed.
